Extended and lowered frame arrangement for motorcycle

Abstract

A motorcycle includes an extended and lower frame arrangement, a front wheel coupled to the extended and lower frame arrangement via a front wheel extension member to frontwardly extend a distance between the extended and lower frame arrangement and the front wheel, a rear wheel coupled to the extended and lower frame arrangement via a widen hub assembly to rearwardly extend a distance between the extended and lower frame arrangement and the rear wheel, such that the front wheel and the rear wheel are shifted far from the extended and lowered frame arrangement to lengthen a distance between the front wheel and the rear wheel so as to further lower a center of gravity of the motorcycle.
